Abstract: 619,118. Liquid meters. AVERY-HARDOLL, Ltd., and FRASER, J. Nov. 22, 1946, No. 34703. [Class 69 (ii)] [Also in Group XXIV] In a liquid meter of the kind in which each uf a pair of cylinders 16, 17 is provided with a piston 36 reciprocated therein by supplying liquid under pressure alternately to opposite ends of the cylinder, the pistons being slidable on rods extending coaxially through the cylinders and each being provided with a radial projection 54 engaging with a crank or equivalent member 61 so that during its reciprocation each piston is caused to effect an angular oscillating movement about the axis of the cylinder, which movement is used to control co-operating ports 25-28 in the cylinder and ports 46-51 in the piston, to connect each end of the cylinder alternately to an inlet and an outlet, the motion of the pistons in the cylinders. is controlled by stationary track rings 53 cooperating with the radial projections. The projections fit within spherical bearing members 55 carried by members 61, mounted for radial sliding movement on gear wheels 62. Springs 63 acting on the members 61 urge ball bearing rollers 67 carried by these members against the track rings. Each gear wheel meshes with a pinion 84 from which a registering mechanism is driven. The track rings are provided with flat portions 73 to 76 so that at each end of their stroke the pistons perform a pure angular movement. The rings are adjustable by means of abutments 77, 78 to vary the stroke of the pistons. This is effected either by deforming the rings or, where the rings comprise two substantially semi-circular portions overlapping one another, by varying the relative positions of the two ring portions. Abutments 78 carry worm-wheels 81 co-operating with worms 82 on a shaft 83. The meter cylinders are supported in a fluid-tight chamber (not shown) into which liquid which is to pass through the meter is delivered by a pump. The rods on which the piston slide (not shown) are located in end caps of the cylinders, the caps having slightly conical spigot portions which enter and are an interference fit in the cylinder ends. Each piston comprises two concentric hollow cylinders 37, 38 and the annular space between the cylinders is divided into four passages 42-45 by radial webs 41. Passages 42, 44 are closed at one end and passages 43, 45 are closed at the other.

Title: Process and preparations for conditioning soil
IPC: C09K17/28
Filed: 1959-10-15
Abstract: 889,216. Soils stabilization. KATCHALSKY, A., BURSZTYN, I., RIM, M., and VOFSI, D. Oct. 15, 1959, No. 34949/59. Class 68(1). Arid soils are conditioned by providing in situ discrete grains or lumps of soil agglutinated by a nitrogenous hardening binder applied in aqueous solution or dispersion. Suitable binders are aqueous solutions of urea-formaldehyde resin, particularly those which in a nephelometric test require the addition to 5 c.c.. of from 2 to 20 c.c. of a 30% by weight aqueous sodium acetate solution at 18‹C. to assume standard opacity, i.e., invisibility of a mark through a 3 mm. layer of the solution. Other binders mentioned are water soluble melamine formaldehyde condensation products, dicyandiamide formaldehyde condensation products, guanidine formaldehyde condensation products and mixtures of such resins prepared by mixing them in various ratios in the course of condensation, and/or after their production. Water soluble or water miscible nitrogenous condensation products are usable. A mixture of 40 kg. of bone glue with 60 litres of water and 5 kg. of urea is stated to be suitable. Discrete drops of the binder are distributed over the soil, in a density which is determined according to the conditions to be corrected or stabilized. To prevent desert soil or sand from shifting, drops spaced at 10 cm. to form lumps at that spacing is effective. To prevent rain erosion, the spacing is denser and the lumps are preferably formed in rows running transversely to the slope. For moisture conservation, the spacing is still closer forming a complete cover. The nitrogen in the binder is available for vegetation growth.
